Ed and Jillian

The Bachelorette's Jillian Harris and her fiancé Ed Swiderski deny reports that he is a cheater.

Us Weekly reports that Ed slept with former girlfriend Lindsey Johnson just days after he popped the question to Jillian. On Wednesday's Good Morning America, Johnson also said that Ed emailed her while he was filming, and exited the show soon after citing the need to get back to work. But another former flame, 24-year-old Betheny Steffen, claims to Us that she slept with Ed before he returned two weeks later to win back Jillian's heart.

"It's he said, she said... Ed is not deceiving me," Jillian told GMA. "Ed is not pulling the wool over my eyes. And lastly, if there was an issue, I'm not going to deal with it in this matter with tabloids and rumors."
